 * 自定义属性工具类

 * 注意： 宽高都为 match_content 且无实际内容时构造方法不会调用
 * 使用方法：
 * xxx extends Component
 * 获取自定义属性：
 * String count = AttrUtils.getStringFromAttr(attrSet,"cus_count","0");
 * <p>
 * 属性定义：
 * 布局头中加入  xmlns:hap="http://schemas.huawei.com/apk/res/ohos" 使用hap区分自定义属性与系统属性
 * 即可使用 hap:cus_count="2"  不加直接使用ohos:cus_count="2"
